Abstract

The purpose of this study is to develop a better understanding of the interface reaction between hydroxylapatite and CoCrMo alloys. Hydroxylapatite powder was sintered onto rods of the alloys by hot isostatic pressing at 900, 1000 and 1100°C at a pressure 120MPa. The reaction at the interface between the components was monitored with EPMA line scanning technique. EPMA analysis on the interface between hydroxylapatite and CoCrMo alloy showed interdiffusion profiles of all the hydroxylapatite and alloy elements and Cr accumulation at the interface. This finding suggests that there was an interfacial bonding provided by diffusion and reaction.
